Are we secure—or are we just hoping we are?
Most growing businesses have bits and pieces in place: MFA for a few accounts, some endpoint tools, a firewall rule nobody wants to touch, maybe a scan that runs occasionally. On paper, it sounds fine. In reality, security is spread across tools and people, and no one has the full picture.
Then a customer sends a vendor security questionnaire. Procurement asks for proof. Sales wants speed. IT starts guessing what’s “true enough.” Leadership is asked to sign off anyway. In the Netherlands, this moment tends to come earlier, and more often, because vendor due diligence is simply part of how business is done.
Sunbytes CyberCheck pulls that scattered reality into a clear baseline and a prioritised roadmap, so security stops being a scramble and becomes a process you can control.
What is Sunbytes CyberCheck?
Sunbytes CyberCheck is a human-led security baseline and roadmap for growing businesses. We help you understand what’s in place today, what’s missing, and what to fix first—so security becomes manageable, and vendor due diligence stops turning into last-minute chaos.
What Sunbytes CyberCheck Includes
- Executive Summary: key findings, major risks, and recommended priorities
- Scope & Approach: what we reviewed (systems, platforms, and core security practices)
- Baseline Maturity Assessment: a clear snapshot of your current posture and control maturity
- Gap Analysis: missing or inconsistent controls, vulnerabilities, and weaknesses
- Risk Evaluation: severity classification and business impact assessment
- Improvement Roadmap: prioritised, actionable recommendations with suggested timelines and ownership
- Leadership-ready visuals: a clear summary of findings and recommendations for decision-makers
- Live readout session: we walk through results, discuss implications, and agree remediation priorities
- 18 security domains covering people, process, and technology
- 150+ checks/safeguards (tailored to your scope and environment)
- Evidence-based scoring per domain, so progress can be tracked over time
This gives you two things most companies are missing: a baseline you can defend, and a prioritised view of what to fix first—without drowning in noise.
What we assess
Sunbytes CyberCheck focuses on the areas customers, buyers, and internal leadership care about most—especially when third-party risk is on the table:
- Identity & access (MFA, admin access, joiners/movers/leavers)
- Asset visibility & ownership (what you run, who owns it)
- Secure configuration (hardening and safe defaults)
- Vulnerability & patch management (how you find and fix issues)
- Logging & monitoring readiness (what you collect, retain, and review)
- Backup & recovery (resilience, restore confidence)
- Incident response readiness (roles, steps, and escalation)
- Data protection basics (encryption, retention, secure deletion)
- Supplier / third-party risk basics (critical vendors and subcontractors)
- Secure change practices (how changes are controlled—especially for product teams)
The goal isn’t to build a “perfect” program overnight. It’s to give you a clear baseline and a realistic plan your team can maintain.
Why Sunbytes CyberCheck exists
Most businesses don’t invest in security because they love frameworks. They invest when the risks become real: downtime, lost customer trust, delivery disruption, or deals that start moving slower because buyers need reassurance.
The problem is that many growing teams aren’t “doing nothing”—they’re doing a bit of everything. A few tools here, a few policies there, some fixes when something breaks. But without a baseline, it’s hard to answer three basic questions that leadership and customers care about:
- Where do we stand today? (not guesses—facts)
- What matters most to fix first? (based on business impact)
- Can we prove it consistently when asked? (evidence, ownership, repeatability)
That’s where Sunbytes CyberCheck fits: it turns scattered efforts into a clear baseline and a prioritised plan you can control, so security becomes a managed process, not a last-minute scramble.
If vendor security questionnaires are the trigger that keeps slowing deals for your team, we break down that specific pain here: Security Questionnaires: The Hidden Deal Blocker for SMEs (Especially in the Netherlands)
Who Sunbytes CyberCheck is for
Sunbytes CyberCheck is designed for growing businesses that need clarity and momentum—without turning security into a full-time internal program overnight.
You’re a strong fit if:
- You sell to mid-market/enterprise customers and vendor due diligence is becoming routine
- Security questionnaires keep showing up late in the sales cycle, slowing down sign-off
- You have security “pieces” in place (tools, settings, processes), but no single baseline that ties it together
- Ownership is unclear (sales asks, IT answers, leadership approves—everyone is involved, nobody owns the full story)
- You want to reduce risk in the right order, not chase every alert or checklist item
- You’re lean on security headcount and need a practical roadmap before hiring or buying bigger solutions
In markets like the Netherlands, procurement and risk teams often expect structured answers and evidence earlier in the process, so getting a baseline becomes a growth enabler, not just a security task.
How Sunbytes CyberCheck works (typical timeline)
Week 1 — Scope & discovery
We confirm what’s in and out, who the stakeholders are, and what systems and processes matter most. We also review any existing security documentation and buyer requirements (including vendor questionnaires, if you have them).
Week 2 — Assessment & validation
We assess evidence across the in-scope domains, validate how controls work in practice, and identify gaps with business context—so findings aren’t just “technical observations,” but clear risks and decisions.
Week 3 — Roadmap & alignment
You receive the executive summary, scorecard, evidence map, and prioritised roadmap. We run a live readout session to walk through the results, answer questions, and agree owners and remediation priorities.
(Timeline can be adjusted based on scope and availability.)
Where scanning, penetration testing, and SOC fit
Sunbytes CyberCheck doesn’t replace scanning, pen-testing, or a SOC. It makes them more effective—because you’re no longer guessing what matters most.
- Vulnerability scanning is great for broad coverage, but it won’t tell you what to prioritize without context.
- Penetration testing is great for deep testing of high-risk systems, but it’s not designed to create an overall programme roadmap.
- SOC / managed monitoring is great when you need 24/7 operations at scale, but it gets expensive if priorities and fundamentals aren’t clear.
CyberCheck gives you the baseline and roadmap first, so you can choose the right combination, in the right order, and explain it clearly when customers ask.

FAQs
Typically a few focused sessions with the right owners (IT/ops/leadership), plus access to existing documentation and evidence. We keep it practical and minimise disruption.
That’s normal. Buyers don’t expect perfection—they expect clarity. We document exceptions, explain the risk in business terms, and provide a realistic remediation plan
No. Sunbytes CyberCheck is designed to prioritise. The output is a roadmap with owners and time horizons, not an overwhelming checklist.
Yes. CyberCheck gives you the baseline and evidence map that makes responses faster and consistent. If you need support for a specific questionnaire during a live deal, we can help with packaging answers and evidence.
No. Compliance mapping and audit-ready evidence (ISO 27001 / DORA / PCI / HIPAA) are handled under Sunbytes Compliance Readiness.
